Tamiya XV-01 Aluminum Rear Lower Suspension Arm by JAZRIDER XV01-13405-LB  [XV01-13405-LB]

Aluminum rear lower arm for XV-01

This aluminum rear lower suspension arm is an RC-scale replacement part intended for the Tamiya XV-01 platform. It serves as a direct swap to the stock plastic arm where chassis geometry allows, offering a metal alternative for hobbyists focusing on durability and consistent suspension behavior during practice runs, track sessions, and tuning work.

Install notes: use the existing mounting pins and hardware from the original arm where compatible, check fit at the hinge pin and wheel hub interface before final tightening, and confirm wheel offset and toe settings after installation. Because this is an aluminum component, small differences in fit or clearance can appear compared with the original plastic parts; make incremental adjustments rather than large changes when reassembling the rear suspension.

Tuning role: replacing the stock arm with an aluminum unit provides a firmer rear end response and more repeatable suspension geometry under load, which helps when testing roll centers, anti-squat settings, and rebound behavior. Pairing this arm with matched rear uprights and properly rated shock settings will let you evaluate handling changes more reliably during setup sessions.
